Problems solved by technology

Initially, infrared light was used and an external light source was used to illuminate the surface of the detected skin. However, infrared detection instruments are not commonly used in daily life, and the external light source often limits the size of the irradiation and detection area, thus affecting the scope and accuracy of detection.

Abstract

The invention discloses a non-contact oxyhemoglobin saturation measuring device based on an imaging device. The device is mainly used for measuring non-contact oxyhemoglobin saturation. The device is composed of a video collecting unit, a signal processing unit and an oxyhemoglobin saturation result displaying unit. The video collecting unit is composed of two CCDs and a video image collecting card which is connected with the CCDs through a data line, wherein the CCDs are located before the human face and are provided with optical filters with different wave sections. The signal processing unit is composed of a PC host machine or a high-speed signal processing circuit. The video information including the human face is collected through the video collecting unit and is transmitted to the PC host machine or the high-speed signal processing system through the data line to be processed in a data mode, pulse waves can be drawn by calculating the change of grey average, in a time domain, of the human face area in a video image, and an oxygen saturation value can be obtained by calculating the two pulse waves with the different wave sections. The calculated result is displayed on the displaying unit through the data line.

Description

technical field [0001] The patent of the present invention relates to a real-time blood oxygen measurement device based on imaging equipment, which is mainly used for non-contact blood oxygen saturation measurement under daily ambient lighting conditions. Compared with the current blood oxygen saturation measuring device in clinical and daily use, the device has strong anti-interference ability, common equipment, simple operation, and no contact with the tested person at all. It is suitable for burns and is not suitable for contact oximeters. patient. It is more suitable for ordinary people to use for health monitoring in daily life. Background technique [0002] Blood oxygen saturation (Oxygensaturation, SO2) is one of the important physiological parameters. Too low blood oxygen saturation will cause irreversible hypoxic damage in human tissues. Therefore, it is very important to monitor it during anesthesia and surgery. important. The methods currently used for daily bl...
